Srinagar: Amid peak winter, Jammu and Kashmir valley is reeling under ‘severe low voltage issues, official said.
The official further said that the heating load is also picking up during early morning and night hours. “The demand may further increase in the coming days.”
It also said that the severe voltage in Jammu and Kashmir is in violation of N-1.
N-1 in power systems is a security criterion ensuring that the grid continues to operate reliably without interruption, even if a single critical component like a generator, line, or transformer fails
“As expected, with the increase in winter, demand of J&K control area is on a higher side and it is hovering around 3200MW,” reads an official document .
It also reads that “It has been observed that the 400kV as well as 220kV Bus voltages at various stations in Kashmir valley are remaining critically low also reaching 347kV and 178kV—well below the Indian Electricity Grid Code (IEGC) band that is 380KV & 198kV respectively due to low hydro generation and heavy Megavolt-Amperes Reactive (MVAR) drawl from the Inter-State Transmission System (ISTS) nodes.”
An official said that J&K SLDC was requested to take appropriate measures to maintain the 400kV & 220kV voltages within IEGC band in J&K control area to avoid any untoward incident. “For the installation of Capacitor Banks in the leftover Grid Substations without reactive devices, a source of funds shall be explored.”
The official documents further reveal that in this backdrop NRPC has asked the authorities of J&K to obtain a detailed input, primitive for additional bus transfer from the field units of these old 220kV Substations. “Accordingly, final details shall be communicated to the Commission.”
The commission had also asked the JKTPCL to expedite measures to improve the severe low-voltage issue in J&K grid—
